Carmex Spiral Mill Threading Insert - Metric/ISO - H63I2.0ISOMT7

The Carmex Spiral Mill Threading Insert is a metric/ISO threading and milling solution built around a spiral design that enables smooth cutting at higher feed rates, helping you finish jobs faster with less downtime.

From small components on compact machining centers to heavy-duty work on high-power mills, this system is engineered for a wide range of applications. The spiral fluted toolholders hold 1 to 9 inserts in a comparatively small cutting diameter, and the unique clamping method ensures optimal indexability for quick, repeatable tool changes. Spiral tooling also helps reduce vibration and chatter to deliver reliable finishes across threading, end milling, roughing, and finishing operations.

• Vibration- and chatter-reducing spiral design: The spiral geometry minimizes vibration for stable finishes and predictable results across different materials and feeds.
• Flexible insert capacity with precise indexing: Toolholders accommodate 1–9 inserts in a small diameter, with a unique clamp that ensures optimal indexability for consistent, repeatable threading and milling.
• MT7 Sub-Micron TiN-coated inserts for universal materials: Inserts use MT7 sub-micron grade with Titanium Nitride multi-layer coating (ISO K10-K20), a general-purpose option that delivers wear resistance and a high-grade finish for threading, roughing, and finishing.

In practice, this spiral threading system helps you improve workflow by enabling fast, reliable threading and milling with consistent results, reducing downtime between tool changes, and delivering finish quality you can trust across a wide range of materials.
